This past December, NASA 3D printed a working tool for the first time in outer space, using a 3D printer that was built with the help of Made In Space. That tool was a fully functional wrench, and after it was successfully tested from the International Space Station, NASA released the files for anyone to download and 3D print themselves.
This wasn’t the first 3D printed tool to be created. We’ve seen plenty of them, ranging from other wrenches to pliers, scissors, and more. As time goes on, individual designers learn what works and what doesn’t work when it comes to 3D printing, and they use this knowledge to come up with designs of their own. One of these designers is a man named Dr. John Steuben, and he has created a design for several 3D printable tools, including a pair of adjustable groove-joint pliers.
